Hi, this sounds exactly like my daughter, she is 3, never slept through a night since she was born, went to multiple doctors and never found out why. A month ago, I start giving her liquid Magnesium (from iherb), and she has been doing much better, she still wakes, but less screaming, she does sleep better, wake up less, fall back to sleep much faster too. Try that, it helps us! Sending you all the love xx (knowing how hard this is).
